Patent attributes
A computer-implemented method for processing radar return signals to identify spherical objects from within a cluster of objects, collects by a radar receiver, a plurality of radar return signals over N-point measurement windows corresponding to objects within the cluster of objects, the radar return signals corresponding to electronic pulses transmitted by a radar transmitter. The radar processor extracts radar cross section data from the collected plurality of radar return signals, and computes, based on the radar cross section data, a plurality of standard deviation values, each standard deviation value based on the radar cross section data corresponding to one of the N-point windows. The radar processor determines, based on analysis of the sequence of standard deviation values of the return signals, whether the object is a spherical object.
